Professor Ishiguro believes that it may prove possible to build an android that could pass for a human, if only for a brief period.
“An android could get away with it for a short time, 5-10 seconds. However, if we carefully select the situation, we could extend that, to perhaps 10 minutes,” he said.

“More importantly, we have found that people forget she is an android while interacting with her. Consciously, it is easy to see that she is an android, but unconsciously, we react to the android as if she were a woman.”
